7 Ways Microsoft Uses AI to Make You Actually Care About Bing

It isn’t just ChatGPT on the Bing website. Microsoft blends OpenAI’s language technology with its own Bing search engine.

Microsoft Bing faces a big problem: Google utterly eclipses search engine. But Bing has a chance to grab more attention for itself with the OpenAI‘s language technology, the artificial intelligence foundation that’s made the ChatGPT service a huge hit.

For the brainier Bing to work, though, Microsoft has to get the details right. ChatGPT can be useful, but it can be flaky, too, and nobody wants a search engine they can’t trust.

Microsoft has put a lot of thought and its own programming resources into the challenge. It’s wrestled with issues like how AI-powered Bing shows ads, reveals its data sources, and grounds the AI technology in reality so you get trustworthy results, not the digital hallucinations that can be hard to spot in machine-generated information.

I spoke to Jordi Ribas, leader of Bing search and AI, to dig more deeply into the overhauled Bing search engine. He’s a big enough fan that he used the technology to help him write his boss a memo about it. «It probably saved me two to three hours,» he said, and it improved the Spanish executive’s English, too.

When the technology expands beyond today’s very small test group, it’ll let millions of us dig for much more complicated information, like whether an Ikea loveseat will fit into your car. And we’ll all be able to see whether it truly gives Google a run for its money. But for now, are seven aspects of Bing AI that I learned.

Bing AI isn’t just a repackaged version of ChatGPT

Microsoft blends its Bing search engine with the large language model technology from OpenAI, the AI lab that built the ChatGPT tool that’s fired up excitement about AI and that Microsoft invested in. You can get ChatGPT-like results using Bing’s «chat» option — for example, «Write a short essay on the importance of Taoism.» But for other queries, Bing and OpenAI technology are blended through an orchestration system Microsoft calls Prometheus.

For instance, you can Bing, «I like the band Led Zeppelin. What other musicians should I listen to?» OpenAI first paraphrases that prompt to «bands similar to Led Zeppelin,» then repackages Bing search results in a bulleted list. Each suggestion, like Fleetwood Mac, Pink Floyd and the Rolling Stones, comes with a two-sentence description.

Bing AI cites its sources — sometimes

When you give ChatGPT a prompt, it’ll respond with text it generates, but it won’t tell you where it got that information. The AI system is trained on vast amounts of the information on the internet, but it’s hard to draw a direct line between that training data and ChatGPT’s output.

On Bing, though, factual information is often annotated, because Bing knows the source from its indexing of the web. For example, in the Led Zeppelin prompt above, Bing includes a link at the top of its answer to a Musicaroo post, 13 Bands That Sound Like Led Zeppelin, and includes that link and others from MusicalMum and Producer Hive.

That sourcing transparency helps address a big criticism of AI, making it easier to evaluate whether the response is accurate or a mere AI hallucination. But it doesn’t always appear. In the essay on Taoism above, for example, there aren’t any sources, footnotes or links at all.

Some source links are ads that make Microsoft money

The Bing AI’s elaborate answers provide a new way for Microsoft to generate money from ads. In traditional Bing searches, the «organic» search results that Bing judges to be most relevant are separate from items placed by advertisers. But with Bing AI searches, the two types of information can be blended.

For example, in its response to the query «plan me a one-week trip to Iceland without a rental car,» AI-powered Bing suggests several destinations. In one of them, several words are underlined: «You can visit places like Vík, Skógafoss, Seljalandsfoss, and Jökulsárlón glacier lagoon by joining a multi-day tour or taking a bus.» Hovering over that link shows three sources for that information and an ad from a tour company. The advertisement is the top item of the three and is labeled «ad.»

«When you look at those citations, sometimes they are ads,» Ribas said. «When it’s more of a purchasing intent query, you hover over it and you’ll see the list of the references and sometimes it’s an ad. Then sometimes in the conversation itself, you’re going to see product ads, like if you do a hotel query.»

Ad revenue is a big deal, since it takes weeks of work on an enormous cluster of computers for OpenAI to build a single update to its language model, and OpenAI CEO Sam Altman estimates it costs a few cents to process each ChatGPT prompt. Bing, even though it’s a distant second to Google in the search engine market, still handles millions of queries a day.

Google plans to open access to its Bard AI chatbot soon, but it won’t be including ads to begin with.

OpenAI-boosted results are more relevant than plain old Bing

The fundamental measure of a search engine’s usefulness is whether its results are relevant, and the OpenAI technology brings a huge boost in the measurement that Microsoft uses to score its search engine results’ relevance.

«My team, working super, super hard in a given year, might move that metric by one point,» Ribas said, but OpenAI’s technology boosted it three points in one fell swoop. «It’s just never happened before in the history of Bing,» Ribas said.

That relevance boost is just for ordinary search results, Ribas added. OpenAI’s technology can further improve Bing with its chat interface that offers more elaborate answers and a follow-up exchange.

OpenAI makes Bing better with languages besides English

One particular area where Bing has been weak is searches that aren’t in English, and Ribas said OpenAI helps there. A lot of Bing’s three-point gain in relevance scoring «came from international markets,» Ribas said.

OpenAI’s large language model, or LLM, is trained with text from 100 languages. «Catalan is my first language. I can have a dialogue in Catalan. It works really, really well,» Ribas said

Bing brings OpenAI’s results up to date

Large language models like OpenAI’s GPT-3.5, the foundation for ChatGPT, are slow to build and improve, which means they don’t move at the speed of the web or of conventional search engines. GPT-3.5, for example, was trained in 2021, so it doesn’t have any idea about Russia’s invasion of Ukraine, the effects of recent inflation on consumers, or Xi Jinping securing his third term as general secretary of the Chinese Communist Party.

Bing often does know this more recent information, though. «When you bring in the Bing results, then you will get fresh results on that complete answer,» Ribas said.

Bing ‘grounds’ OpenAI’s flights of fancy

Microsoft uses its Bing data to try to avoid situations where OpenAI’s more creative technology could lead people astray. The more factual a query and answer are, the more Bing’s technology is used in the answer, Ribas said. This «grounding» significantly reduces AI’s problems with making stuff up: «It will reduce hallucination, which is … an ongoing battle,» Ribas said.

But Microsoft doesn’t want its grounding system to squash all the magic out of the AI. There’s a reason ChatGPT has been so captivating. The Prometheus system decides on the priorities for each query.

«We had to find the sweet spot between over-grounding the model and keeping it interesting,» Ribas said. «We have a measurement of the interestingness of the results, and we have a measurement for the groundedness of the results. The more the query is looking for something very factual, the more we weight the grounded. The more the query is supposed to be creative, the less we weight the grounded. I kept telling my team, I want my cake and eat it too.»

Meta Confirms Testing of Premium Instagram, Facebook and WhatsApp Subscriptions

The company says it’s testing paywalled premium sharing and AI features.

People using Instagram, Facebook and WhatsApp may soon need to decide whether they want to pay extra for additional features beyond the free versions they’ve been using.

Meta confirmed that it’s planning to roll out and test premium subscription tiers for its three most popular services, which, according to the company, would unlock «special features and more control over how they share and connect,» according to a TechCrunch report detailing the changes.

A representative for Meta did not elaborate on subscription plans, but confirmed to CNET that TechCrunch’s story is accurate.

According to the report, this would differ from the Meta Verified badge offering aimed at businesses and internet content creators. Meta Verified starts at $15 and includes enhanced support options and protections against impersonation.

Instead, the new subscriptions that Facebook, Instagram and WhatsApp users can expect will offer a broader Premium experience, but it’s unclear so far which specific features will be included. According to TechCrunch, AI will be a part of that mix with potential paywalls or extra access to AI image generators or AI agents as part of its plans. What bundles and subscriptions are offered could change based on customer feedback, Meta told TechCrunch.

Subscriptions for once-free social media services are now common, with LinkedIn, X (formerly Twitter) and Snapchat all giving people the option to pay more for extra features.

Garmin Venu 4

Pros

  • Week-long battery life in smartwatch mode
  • Polished circular design
  • Advanced fitness and recovery metrics

Cons

  • $100 more than previous generation
  • Software can feel sluggish
  • UI is not as intuitive as other smart watches

Until the Garmin Venu 4 landed on my wrist, I mostly shied away from using dedicated sports watches from brands like Garmin or Polar as my daily driver. Part of that was imposter syndrome; I’m a fitness enthusiast, not a full-blown athlete (yet). But mostly, I wasn’t willing to accept the trade-offs that came with them: clunky software, limited smart features and designs that felt more like gym gear than something I’d want to wear all day.

The Venu 4 isn’t the only good-looking sports watch on the market, but it’s the first one that’s come close to convincing me to go all-in. It’s well-rounded (literally and figuratively) and packed with fitness features that don’t feel condescending to an athlete wannabe like me.

The line between sports watches and traditional smartwatches seems to get blurrier each year. Both Apple and Samsung now have rugged Ultra smartwatch lines, and sports watches are starting to look (and act) more like traditional smartwatches.  

The Venu 4 feels like Garmin’s strongest attempt yet to bridge these two worlds. It goes all out on fitness features with advanced insights like training readiness and suggested workouts typically reserved for the top-tier Fēnix models, but has a design and a price that are approachable for people who live somewhere between casual fitness enthusiast and aspiring athlete. 

The $550 price (for both 41mm and 45mm models) is $100 more than its predecessor, and upgrading from the Venu 3 makes sense only if you plan to use the data it provides. If you’re someone who mostly just wants the occasional workout tracking, then the Venu 4 will be overkill. 

I may not be a full convert (yet), but after weeks of living with it day and night with the Venu 4, I get the Garmin obsession, and I can see how a sports watch could help me level up my fitness journey when I’m ready. 

Venu 4 fitness: Garmin’s core strength

The Venu 4 supports what feels like every workout imaginable, from running and cycling to rowing, HIIT, and even golf course mapping. It supports multi-band GPS, which I found provided more accurate location tracking, even on trail runs without my phone. Heart rate tracking stayed impressively close to my Polar chest strap after the initial jump from resting to higher-intensity sprint.

Garmin’s strength isn’t just the sheer volume of data it collects, but how it helps you understand how those metrics impact your training. On the Venu 4, you get heart rate, breathing rate, blood oxygen, stress, ECG, skin temperature changes, HRV, and advanced sleep and menstrual cycle tracking.

On their own, these metrics can feel overwhelming or even meaningless. What Garmin does especially well is connect the dots through features like Body Battery, Training Readiness, Load and other recovery insights that translate raw data into a clearer picture of how prepared your body is for activity. And because you’re not constantly taking it off to charge, Garmin can build a more complete picture of your health and recovery that becomes more accurate over time.

I found waking up to a low Body Battery score when I felt off was both depressing and validating: no, I probably can’t just «shake this one off,» and yes, I should probably take a rest day (or two) before getting back to that New Year’s resolution. 

The watch also highlights when you’re theoretically at your best to work out, even if real life doesn’t always cooperate. There’s no greater irony than seeing I’m in «peak» training readiness while rocking my toddler to sleep, or hustling to get a story in on time. That’s ultimately my biggest barrier to fully crossing over into the Garmin ecosystem. I’m not always in a position to follow the advice that makes these metrics most valuable.

Garmin Connect Plus subscribers ($7 per month) get access to personalized coaching plans and daily suggested workouts that adapt based on their sleep, recovery and activity history. I tried a running plan to prep for a 10K, but by day three, I’d gone rogue and settled back into my tired, but realistic, workout routine. Learning new routines takes time, and at this stage of life, 20-minute workouts squeezed between everything else will have to suffice.

Venu 4 battery life: Amazing for a smartwatch, but meh for a Garmin

The Venu 4’s shiny new upgrades (brighter display and improved GPS tracking over the Venu 3) come at a slight cost to battery life: You get 12 days on the Venu 4 versus 14 on the Venu 3. But I think it’s well worth it when you factor in everything else it has. 

I averaged about 10 days of battery life per charge for the smaller 41mm Venu 4 that I tested. But that’s in smartwatch mode, which disables the always-on display. If, like me, you prefer the always-on display, battery life drops. I got roughly four days on a charge (slightly less on long hiking days when the GPS was running). It’s not quite multiweek endurance like Garmin’s Enduro or Instinct lines. But even at the lower end, the Venu 4 is still far better than most Apple and Samsung watches.

I’ve never worn a smartwatch this long without taking it off for a charge, which turns out can be both a good and a bad thing. On the plus side, it made sleep tracking more consistent, which is key to unlocking Garmin’s best features like Body Battery, HRV (heart rate variability) and recovery insights. Wearing the watch for so long is also important for identifying long-term health trends and detecting early signs of illness.

The flip side of wearing it nonstop was skin irritation. After about five straight days, the skin directly under the watch became red and itchy. I tried to power through it, which only made things worse. A perfect storm of winter weather, a suppressed immune system, and the polymer backing on the underside of the watch likely didn’t help matters. After taking a week off, cleaning it more regularly, and giving my skin the occasional break, the issue hasn’t returned. And if you have sensitive skin like me, it’s probably worth building in a little breathing room.

Venu 4 design: Not your average sports watch 

The Venu 4 is hands down one of the best-looking watches I’ve tested (Note: I didn’t say sports watches). It even earned its fair share of compliments from friends who didn’t know it was a sports watch. The Venu 4 comes in two sizes, 41mm and 45mm, both with a 1.4-inch AMOLED screen and a stainless steel case in lunar gold, slate, or silver finishes. It’s covered in Gorilla Glass 3 and has a fiber-reinforced polymer back.

The bezels are larger than those on an Apple Watch Series 11, and the usable screen area feels smaller than expected. The Venu 4’s display is bright and legible even in direct sunlight. You might not find it as responsive to touch if you’re coming from an LTPO OLED or Super AMOLED display with a higher refresh rate, like those on Apple or Samsung watches. Which is why the physical button navigation is so important. 

Garmin slimmed the design down to two physical buttons (the Venu 3 had 3). One button brings up navigation, while the other handles quick settings. Long-pressing the bottom button activates other actions, like the flashlight, but until muscle memory kicks in, it’s easy to forget which one does what. 

The built-in LED flashlight is a standout feature. It’s an actual light embedded in the side of the watch, not a screen-based workaround like found on other smartwatches. It’s surprisingly powerful and incredibly useful, whether you’re doing an ultramarathon or, in my case, checking on a sleeping kid without turning on any lights.

Venu 4 watch basics: Functional, but not seamless

On paper, the Venu 4 checks most of the smartwatch boxes. It has notifications, mobile payments via Garmin Pay, music storage, voice assistant access (via your phone) and supports calls from your wrist. Android phone owners get the added perk of responding to texts from the watch; iPhone owners are out of luck.

In my testing, this is where Garmin still lags behind true smartwatches. Everything works, but it’s not seamless; simple actions often take more steps than they should, and Garmin’s app ecosystem remains limited. Even changing your watch face requires an additional phone app (Garmin IQ). The upside is cross-platform compatibility, and aside from the ability to respond to texts, the experience is consistent across iOS and Android.

Venu 4 accessibility features

Garmin has also added more accessibility options in the Venu 4. There are spoken watch faces that read out time and health data, hourly audio alerts, and multiple color filters for people with color blindness.

Venu 4: Final thoughts 

I’m still a practical generalist in the throes of working motherhood, but the Garmin Venu 4 is the closest I’ve been to going full sports watch. If I were ready to make fitness a true priority, the Venu 4 would be my gateway Garmin watch. 

It’s a solid pick for anyone looking to cross over into the sports watch world for the first time, and it’s one of Garmin’s most well-rounded options. The Venu 4 has enough battery to get you through the week, training insights that feel genuinely helpful rather than overwhelming, and a design that’s polished enough to pass for date-night-ready.

Marathon: Release Date, Open Preview Weekend and More

Bungie’s extraction shooter has a new release date, and it’s coming soon.

Marathon is the next game from Bungie, the acclaimed studio behind the Halo and Destiny franchises. The developer’s new game was originally set to come out last September, but the lukewarm reception it received from players who tried out the game’s alpha test led Bungie to delay the release to give it some fine-tuning.

It appears Bungie is ready to try again, as it confirmed that Marathon will be released this March. The company revealed the new release date on Jan. 19, when the pre-order trailer for the game was uploaded to YouTube

When does Marathon come out? 

Marathon will be released on March 5 for PC, PS5 and Xbox Series X|S consoles and will cost $40.

Will there be a Marathon playtest? 

Yes. The official Marathon X account posted on Jan. 19 that there will be an open preview weekend before the game’s launch. 

What is Marathon? 

Marathon is an action first-person shooter series developed by Bungie, first released in 1994 for the Apple Macintosh. It and the following two games of the original Marathon trilogy are science fiction mysteries set in the 28th century, when humans travel across space in starships. One of them, the UESC Marathon, is attacked by aliens until only a lone security guard, the player, is left to fight them off. Players discover that the ship’s artificial intelligence, called Durandal, has gone sentient and evil, and even called aliens to attack the ship. The following games have players uncovering the mysteries behind Durandal and other ancient AIs that have been manipulating alien races. 

The series was Bungie’s first hit, and it was innovative in its time for revealing story segments through computer terminals, where you could read messages from the different AI running the ship, as well as crew diaries. 

In this new version of Marathon, players will visit Tau Ceti IV, the planet that humans from the UESC Marathon settled. The year is 2893, and something has caused many of the colonists to disappear. Survivors have formed different groups to savage what they can from the colony. The people doing the savaging are known as «Runners,» who are humans trained in combat and who use cybernetic modifications to survive on the planet. Players will create their own Runner to get loot and learn what happened to the colony as they fight off aliens as well as other Runners. 

What is an extraction shooter? 

An exaction shooter is a type of online multiplayer game where the focus isn’t just about killing enemies or other players. Instead, the objective revolves around scavenging loot and completing missions. 

To make things exciting, players can only extract loot at designated locations in the game world. And to complicate things even further, the start of the extraction process will include some signal that alerts both enemies and players within the vicinity. This means you’ll have to defend yourself for a short period of time from what could be waves of computer-controlled enemies or human players who may or may not try to steal your loot. 

Some of the most popular extraction shooters out right now are Arc Raiders, Escape from Tarkov and Helldivers 2.

How is Marathon related to Halo? 

Marathon was Bungie’s first hit series, but it was Halo that made the developer a household name. While the two game franchises do not have any firm narrative connections, there have always been subtle references to the Marathon games in Halo. Bungie has said that Halo is more of a spiritual successor to Marathon, but there are fan theories connecting Marathon, Halo and even Bungie’s other major franchise, Destiny.
